INVENTOR ATTORNEYS Patented Apr. 18, 1939 UNITED STATES PATENT OFFICE 1Claim.

This invention relates to cream separators and has for an object toprovide a cream separator including a stopper and levers connected tothe stopper by means of which the latter may be tilt- 5 ed and loweredinto or withdrawn from a milk bottle.

A further object is to provide a cream separator having a flexibletapered rubber stopper to continuously conform to the size of the bottleneck 10 when removing the cream.

A further object is to provide a cream separator of this type havinglevers and a stopper the levers being provided at their upper ends withhandles which extend in opposite directions from the 15 levers, thecombined length of the handles being greater than the diameter of theneck of the bottle so that the handles will prevent the device fromfalling completely into the milk bottle.

A further object is to provide a device of this 20 character which willbe formed of a few strong simple and durable parts, which will beinexpensive to manufacture, and which will not easily get out of order.

With the above and. other objects in view the 25 invention consists ofcertain novel details of construction and combinations of partshereinafter fully described and claimed, it being understood thatVarious modifications may be resorted to within the scope of theappended claim without 30 departing from the spirit or sacrificing anyof the advantages of the invention.

In the accompanying drawing forming part of this specification,

Figure 1 is a sectional view of a milk bottle 35 showing a creamseparator constructed in accordance with the invention in appliedposition to remove cream from the top of the bottle.

Figure 2 is a side elevation of the cream separator shown in Figure 1.

40 Figure 3 is a plan view of the stopper showing the levers in section.

Figure 4 is a detail perspective View showing the handles projecting inopposite directions from the upper ends of the levers.

5 Figure 5 is a detail cross sectional view showing one of the hingeears of the stopper and the hook of one of the levers therein.

Referring now to the drawing in which like characters of referencedesignate similar parts 50 in the various views, I designates aconventional milk bottle. As is well known, the cream rises to the topand the milk settles to the bottom. For removing the cream a discstopper I I of substantially the same diameter as the diameter of 5 themilk bottle below the shoulders of the bottle is provided, the stopperpreferably being formed of rubber and being tapered toward the edges soas to be flexible at the marginal edge.

The rubber stopper is provided with spaced hinge ears I2 and I3, theformer being located 5 at the center of the top of the stopper and thelatter being located midway between the center and the peripheral edgeof the stopper as best shown in Figure 3.

A pair of levers I4 and I5 are provided with hooks I6 and I1respectively which are hooked through the hinge ears I2 and I3 of thestopper. These levers are of suflicient length to extend above thebottle when the stopper is lowered to the bottom of the cream in thebottle. As best shown in Figure 4, the upper end of the lever I5 isprovided with an eye I8 which slidab-ly receives the upper end of thelever I4 and from this eye a handle I9 projects at substantially a rightangle to the lever I4. The lever I4 above the eye I 8 is also providedwith a handle 20 which extends at a right angle to the lever and alsoextends oppositely to the handle I9. The combined length of both handlesI9 and 20 is greater than the diameter of the mouth of the milk bottleso that the handles Will prevent the device from falling completely intothe milk bottle.

The handle I9 is provided with a sharpened point 2| to penetrate thepaper stopper of a milk bottle, and the handle 20 is provided with anupturned end 22, for effectively removing the paper stopper of the milkbottle.

In operation the lever I4 may be raised relatively to the lever I5 todispose the stopper II vertical. Thereupon the device may be loweredinto the milk bottle until the stopper arrives at the bottom of thecream. The lever I4 may be then lowered to dispose the stopperhorizontally as shown in Figure 1. The device may then be lifted fromthe bottle, the flexible edges of the stopper yielding to conform snuglyto the neck of the bottle during withdrawal of the device for separatingthe cream from the milk. After the cream has been separated the devicemay be slidably lowered into the bottle and the lever I4 again lifted todispose the stopper II in a vertical position to facilitate easywithdrawal from the neck of the bottle.

From the above description it is thought that the construction andoperation of the invention will be fully understood without furtherexplanation.

What is claimed is:

A cream separator comprising a circular pliable rubber disc taperedtoward the edge and having a center hinge eye and eccentrichinge eye onthe top face, a pair of levers formed of stiff wire hinged at the lowerends to respective ones of said eyes, the lever connected to theeccentric eye sloping toward the lever connected to the center eye andbeing formed at the upper end with a convolution receiving the lastnamed lever, both levers being bent outwardly at a right angle In at theupper end to provide oppositely extending handles, the combined lengthof said handles being greater than the diameter of the neck of a milkbottle and being adapted. to engage said neck and prevent the creamseparator from falling into the bottle, one of the handles terminatingin a sharpened point and the other terminating in a hook, the hook andeye being adapted to effect removal of a paper milk bottle stopperpreparatory to removing the cream.
